Abstract

SE PROPONE UN DESCODIFICADOR DE VIDEO QUE RECIBE LOS PAQUETES DE INFORMACION DE VIDEO RELATIVA AL MOVIMIENTO DE LAS IMAGENES DE VIDEO A PARTIR DE UNA RED DE CONMUTACION DE PAQUETES. DE ACUERDO CON LA INVENCION SE ELIMINAN UNA GRAN CANTIDAD DE GASTOS DE HARDWARE Y SE GANA MUCHA MAS FLEXIBILIDAD COMPARADA CON LOS DESCODIFICADORES DE ESTE TIPO CONOCIDOS HASTA AHORA EN LOS PROCESOS DE DESCODIFICACION, IMPLANTADOS A TRAVES DE MEDIOS (DEC1, DCE2) DE DESCODIFICACION, FUNCIONANDO DE FORMA ASINCRONA CON RESPECTO A LOS PROCESOS DE REPRODUCCION, IMPLANTADOS A TRAVES DE MEDIOS (DIS) DE REPRODUCCION. ADEMAS, Y TAMBIEN EN CONTRASTE CON LOS DESCODIFICADORES ANTERIORES DE ESTE TIPO, EL DESCODIFICADOR DE VIDEO DE ACUERDO CON LA PRESENTE INVENCION NO ESTA EXPLICITAMENTE SINCRONIZADO A SUS CODIFICADORES CORRESPONDIENTES MEDIANTE LA COBERTURA EXPLICITA DE LOS ULTIMOS SISTEMAS DE RELOJ. ESTO SE REALIZA A TRAVES DE ACCIONES DE FRENADO DENTRO DE UNA MEMORIA (FSM) DE ALMACENAMIENTO PRINCIPAL COLOCADA ENTRE LOS MEDIOS (DEC1, DEC2) DE DESCODIFICACION Y LOS MEDIOS (DIS) DE REPRODUCCION. LA LONGITUD VARIABLE DE UN SEPARADOR DE ESTE TIPO PUEDE SER UTILIZADA PARA EL CONTROL DE LA VELOCIDAD DE LOS PROCESOS DE REPRODUCCION A FIN DE PREVENIR EL SUBFLUJO O SOBREFLUJO DE LOS ULTIMOS SEPARADORES Y LA DEGRADACION CORRESPONDIENTE DE LA IMAGEN. ESTO ULTIMO ES REALIZADO A TRAVES DE MEDIOS (CON) DE CONTROL.A VIDEO DECODER IS RECEIVED THAT RECEIVES THE VIDEO INFORMATION PACKAGES RELATING TO THE MOVEMENT OF VIDEO IMAGES FROM A PACKAGE SWITCHING NETWORK. IN ACCORDANCE WITH THE INVENTION, A LARGE AMOUNT OF HARDWARE EXPENSES ARE REMOVED AND MUCH MORE FLEXIBILITY IS GAINED COMPARED WITH THE DECODERS OF THIS TYPE KNOWN SO FAR IN THE DECODING PROCESSES, IMPLEMENTED THROUGH MEDIA (DEC1, DEC2) ASYNCHRONOUSLY WITH REGARD TO REPRODUCTION PROCESSES, IMPLEMENTED THROUGH REPRODUCTION MEANS (DIS). IN ADDITION, AND ALSO IN CONTRAST TO PREVIOUS DECODERS OF THIS TYPE, THE VIDEO DECODER ACCORDING TO THE PRESENT INVENTION IS NOT EXPLICITLY SYNCHRONIZED TO ITS CORRESPONDING ENCODERS OF THE LAST RELATED. THIS IS DONE THROUGH BRAKING ACTIONS WITHIN A MAIN STORAGE MEMORY (FSM) PLACED BETWEEN THE DECODING MEANS (DEC1, DEC2) AND THE REPRODUCTION MEANS (DIS). THE VARIABLE LENGTH OF A SEPARATOR OF THIS TYPE MAY BE USED TO CONTROL THE SPEED OF THE REPRODUCTION PROCESSES IN ORDER TO PREVENT THE UNDERFLOW OR OVERFLOW OF THE LAST SEPARATORS AND THE CORRESPONDING DEGRADATION OF THE IMAGE. THIS LAST IS PERFORMED THROUGH (WITH) CONTROL MEANS.
